1 To all whom t may concern.'

Be it known that I, CHARLES E. BARR1E,'a

citizen of the United States, and a resident Y of Brattleboro, in thecounty of Windham and State of Vermont, have invented a new and ImprovedRoad-Sweeper, of which the following is a full, clear, and exactdescription.

This invention relates to sweepersand has for an object the provision ofan improved construction which may be used for sweeping roads, streetsand the like' under ordinary conditions, or may be used for sweepingsnow or other matterv in considerable quantities.

A further object of the invention is to provide an improved,construction wherein the elevating means extends to a point near theroad so that the sweeping members or collecting members may not raisethe dirt, snow, or other matter. Y

A still further object of the invention is to provide a sweeping andelevating device for a vehicle which will operate to Ycollect the dirtor other matter being swept while the vehicle is moving at anappreciable speed, so that the streets may be cleaned without shutting0E their general traffic.

In the accompanying drawings:

Figure 1 is a longitudinal vertical section through the rear part of themachine Adisclosing an embodiment of the invention.

Fig. 2 is a top plan view on A,line 2-2 of Fig. 1, the same being on areduced scale.

Fig. 3 is a rear view of the structure shown'in Fig. 1.

Fig. 4 is a through Fig. 1 on line 4 4.

Fig. 5 is a detail fragmentary view showing a slightly modified form ofcollecting means wherein a scraper is used instead of a brush. Y

Referring to the accompanying drawing by numerals, 1 indicates the frameof an automobile or other vehicle, the detail features of which form nopart of the present invention. It will, of course, be understood that apower driven vehicle may be used or a horse drawn vehicle withoutdeparting from the spirit of the invention. When the device is mountedon a power driven vehicle power is transmitted from the engine throughshaft 2 to the worm 3, which in turn transmits power to the worm gear 4secured to the transverse shaft 5 rmounted in suitable bearing boxes onthe frame 1.

fragmentary sectional view Y Supported by the shaft 5 are sprocketwheels 6 and 7 which accommodate chains 8 and 9, which chains in turnpass over sprocket wheels connected with the driving or trac-V tionwheels 10 and 11. The wheels 10 and 11 are rigidly secured to tubularstub shafts 12 and 13, which stub shafts are loosely mounted on a fixednon-rotatable bearing shaft 14. VThe stub shaft 13 is connected to theauxiliary shaft 15 through gears 16 and 17 and a clutch 18, which clutchis operated byA lever 19 and rod 20 extending to the front of themachine. The stub shaft 12 transmits power through the gears 21 and 22and the clutch 23 to the auxiliary shaft 24. Clutch 23 is operated by alever 25 which in turn is actuated by rod 26 extending to the front ofthe machine whereby when the rods 20 and 26are actuated the clutcheswill also ber-actuated for turning on and offthepower to theauxiliaryshafts 15and 24. These shafts are supported by suitable bearing .boxescarried by what may be termed the elevator 27, which elevator isprovided 'with a sheet metal base 28 extending from the rear of themachine as shown in Fig. 1 forwardly to the bend 29 and from thenceupwardly to the horizontal, section 30 of the chain 31. Suitablebrackets 32 and 33 are mounted on the axle 14, said brackets beingrigidly secured to the plate 28 in any desired manner whereby the plate:is permitted a swinging movement around the axle l14v and thereby theelevator 27 may move up vand down in passing over inequalities in theroadbed or street.

To provide a proper bearing surface for the plate 28 Va number ofrunners 34 are pro- Ivided which are rigidly secured to the horizontalor bottom sections 35 of plate 28 as shown particularly in Figs. 1 and2. The

`auxiliary shaft 15 has a sprocket wheel 36 rigidly secured thereto,said sprocket wheel accommodating the chain 37, which chain passes overa sprocket wheel 38 mounted on the shaft 39. Shaft 39 carries sprocketwheels 40y and'41, said sprocket wheels accommodating the chain 31 asshown particularly in Fig. 1. The chain 42 passes over a sprocket43 onauxiliary shaft 24 and also one of the sprockets 38 on the'shaft 39. Asprocket 44 is rigidly secured to the auxiliary shaft 24 andaccommodates chain 45, which chain passes over a sprocket 46 operatingthe shaft 47, which shaft rotates the vbeveled gear 48 meshing with thebeveled gear 49. Vleveled gear49 is connected to the may desired, frombrush 50 through a universal joint 51Where.-the spirit .ofthe invention.

A sprocket 52 isconfwishaft 80 carrled by bracket 78, said shaft nectedto the.auxiliary-shaft and accoln-v-v modates a chain 53, which acts similarto chain 45, but rotates the sprocket 54`o`n the ehafeeemllieh eerree,elle, beveled geel." 56- The eeerfe 'meshes ,with .the beveled geef 57.which last mentionedgear rotates the said beveled gear actingthrongh thefuniversal connection 59.
